Jessica, I don't have much on Karl other than a Photo of him sweeping an area in Hadithah. Iraq. I'm am sorry about Karl. He was on the front lines of the war on terror and paid the ultimate price.
I have had several request from people that lost a loved one. They are looking for reasons, looking for answers, I don't have any. War is a brutal business.
Jessica, only time and tears will take away your pain. Remember Karl for who he was and be proud of him. He died advancing Democracy, A noble cause indeed!
Take Care
